I drive both left and right hand drive. I drive left hand drive in US and right hand drive in Hong Kong. To be Honest, it's the same when you are talking about which side is better. The main point is if you get used to that side. For me now both sides are fine for real cars. However, I haven't been driving the right hand drive car in games which means the shift is on the left side. So I can't say for sure about the dominant hand.
